MeGUI: General Questions and Troubleshooting Thread

[Sharktooth]

resolution, fps, bitrate...?

[M.H.A.Q.S.]

The resolution varies as I have tried to encode many movies. The FPS is mostly set to 29.97 and the bitrate for audio and video varies between 50-128. I use AAC audio encoder for audio encoding when there is a need.

Here is the log from x264gui, just for reference.

[sjchmura]

Ok, I want to move from Recode to the High Profile, Dual core support of MeGUI/X264 :)

I have nero 7 installed. Should I use this or another audio method? So far the megui is bombing on the Ac3 so i assume this is due to nero 7 being "locked" from other software.

Is the "directshow" drop down using AVIsynth (read another post). If so how do I ensure the AVIsynth method is being used and updated properly..

[ChronoCross]

Megui no longer supports nero 7. It uses instead their free AAC encoder. try updating to the latest version of megui and use the updater to download the needed files.

[sjchmura]

Wow - never knew the updater works that way :) I thought only StaxRip. Sorry - RFM :)

[M.H.A.Q.S.]

c'mon guys. Does nobody know what is wrong with the encoding done with x264??

[check]

@ MHAQS,if the only problem is that you cannot output to anything but mp4, can't you simply remux the file after it is output?

My question: I've run into no troubles with adaptive muxer, has anyone found any problems with it?

[thuongshoo]

Hi !
I open AVS file.
You know! If I choose 2pass- 1st pass, I can't choose container and video output filename.
I click Enqueue. Megui says " video output filename does not have the correct extention. Based on current settings, it should be mp4"
and for clicking "Queeu analysis pass", Megui says "Error : Could not add job to queue. Make sure that all the details are enterd correctly "

Please help me !
Thank you !

[jellysandwich]

A few questions:

1) Does MeGUI automatically convert .srt subs to .ttxt (I'm worried about a MP4 spec compliant issue)?
2) Why doesn't MeGUI's muxer allow .ttxt subs in the first place?
3) After muxing a file, how can I access the subs in that file? Ie, if I load the file into mmg/mkvmerge, it will see the video and audio streams but not the subtitles.

js

[Doom9]

Does MeGUI automatically convert .srt subs to .ttxt Yes and No. No, MeGui doesn't do that, but mp4box does and since MeGUI uses mp4box...
Why doesn't MeGUI's muxer allow .ttxt subs in the first place?Because srt is pretty much the standard format for textual subs?
3) Do these tools even support all MP4 flavors? I mean the obvious way is to install the appropriate mp4 playback filters and play the file.. not try to remux it into something else. mp4box might be able to extract the subs again (it will certainly list them as a track) but I've never had the need to try this out.

[jellysandwich]

Yep, mp4box can indeed extract it. I was just wondering if it was possible just in case I needed to remux for some reason. Thanks a bunch.

js

[ariga]

The download link to chronocross's site on sourceforge is incorrect.

Is there an alternative to running the autoupdate to get the latest builds ? Often the PC I use to browse doesn't have .Net 2 :(

[daverc]

@ariga : i think MeGui is now hosted on x264.nl

I just noticed there's no obvious way to get MeGUI when you google for it. First answers are doom9 posts, or sourceforge page. And they all are more or less outdated.

It could give a boost to the project if someone puts a link to x264.nl (http://x264.nl) on top of each of these pages.

[check]

The autoupdate server is here: http://megui.org/auto/

[check]

Can someone please explain what "Use Advanced ToolTips" in the options does? Thanks.

[ChronoCross]

Can someone please explain what "Use Advanced ToolTips" in the options does? Thanks.

if you hover over a checkbox it will display an information bubble. if this option is unchecked those do not appear.

[Revgen]

Doesn't Xvid encraw support multithreading?

MeGUI doesn't seem to have any multithreading options to choose from for Xvid. I'd appreciate it if they were added. Thanks. :thanks:

[ChronoCross]

MeGUI doesn't seem to have any multithreading options to choose from for Xvid. I'd appreciate it if they were added. Thanks. :thanks:

xvid encraw does support it however this is a feature part of the 1.2CVS. I'm not sure if megui supports using it yet. Sharktooth or berrinam or even doom9 might know better.

[Revgen]

Okay I'll contact berrinem.

[ariga]

Thanks, daverc & check.

[Blue_MiSfit]

Strange.. I formatted this evening and figured I would give the new MeGUI auto-update thing a try. So I installed the latest build from x264.nl - 0.2.3.2175 - and when it auto updates neroaacenc is not available.

Any word on what's happening, or what a fix could be?


realized I have to get this file myself from nero's website due to licensing issues. All is well


This feature is unbelievably cool. No more digging through the forums and my archives!

Thanks!!!

I try to use version which is at sourgeforce.net. This version allow me to choose container when I choose 2pass-1st pass.



I have new problem ! I have no output file when I finished encoding 2pass-2ndpass.

[Carpo]

ok heres two little questions i think should go here

(note im not asking which is better on this one:) )

1st

which has more support mkv or mp4 - i would like to use the one which is more widely supported

2nd

seeing as i have a few pcs now (wifes childrens) i was thinkning of getting win2k3 standard server and do all the encodes from there (as well as other things)- has anyone used megui on that sort of OS ? if so any issues ?

[Morte66]

which has more support mkv or mp4 - i would like to use the one which is more widely supported

Do you mean "which container supports more content", or "which "container is supported by more players/tools"?

I'd say mkv is better for content. But if a certain piece of software only handles one of them, then it's probably mp4.

[Carpo]

"which "container is supported by more players/tools"?


was what i meant :)

[Doom9]

I try to use version which is at sourgeforce.net.That's a very old revision ---- wait scratch that.. a rather up-to-date is now up but it was just placed there two days ago.. so you should always indicate the revision you're using.
I have no output file when I finished encoding 2pass-2ndpass. Whomever asked that we put a start and end time for a process in there (I initially was opposed to that but now I bow to the wisdom behind this request even though it probably wasn't meant in the same spirit as I find it useful now), inadvertedly added a feature that more people should be aware of:

The log shows you the total processing time for every single job. Armed with that, if video encoding only takes a few seconds.. that should sound an ear-piercing alarm.

Your job3: you can't encode more than 7000 frames in 16 seconds.. it's just impossible. Job4: you can't encode more than 6000 frames 2 seconds.. it's even more impossible.
Add another piece of crucial information: When x264 craps out for some reason, it not always tells megui why it crapped out.. those are the cases when you need to take the commandline from megui, and run the job manually from the commandline.. you're likely to find out what exactly went wrong when you do that. If you don't know what that means, I wrote instructions in the bugreport thread.

[Sharktooth]

I've just updated the SF version to 2177.

so where do I put the neroaacenc so megui recognizes it?

[jellysandwich]

It doesn't matter where you put it. You need to edit the autoupdate.xml file to make it think that it currently has the latest version installed. For example,

<iUpgradeable xsi:type="ProgramFile">
<DownloadChecked>false</DownloadChecked>
<SavePath>D:\encoding\megui\tools\neroaacenc\neroaacenc.exe</SavePath>

<AllowUpdate>true</AllowUpdate>
<Name>neroaacenc</Name>
<TreeViewID>UpdateableFiles.ProgramFile</TreeViewID>
<NeedsRestartedCopying>false</NeedsRestartedCopying>
</iUpgradeable>

I imagine you could just take it out entirely, but I'm not sure. And of course, you could also simply wait for the developers to take care of it.

I'm using MeGUI for the first time and did a quick search of the forum but didn't find a solution, so I thought I'd post. I'm trying to encode my episodes of American Dad. When generating the AVS script, the guide says to use the "Analyze" on the Filters tab to check the source to determine the type and which deinterlacing is required. However, it fails on the one episode that I've tried (S1E12). I'm using v0.2.3.2177 of MeGUI.

This is what it says:


Source type: For your reference:
Progressive sections: 0
Interlaced sections: 0
Partially Static Sections: 137
Film Sections: 14
Source does not have enough data. This either comes from an internal error or an unexpected source type.


Then the only option is "Do nothing (Source Detection is stuck)".

I tried checking the deinterlace box, but of course there was nothing in the AVS script. I went ahead and encode the episode, but the source output was interlaced as expected. If I deinterlace using ffdshow, it sort of works. But I've noticed that the various deinterlacers have trouble with these episodes (I've tried AutoGK and several different deinterlacing methods in GK).

Is there a way to select the deinterlacing in the GUI? I don't know anything about AVS scripts, so I wouldn't know how to add a deinterlacing method manually.

Any help is appreciated.

[berrinam]

Two suggestions:
Try bautodeint (http://forum.doom9.org/showthread.php?t=111870&highlight=bautodeint) to see if it recommends anything. Unfortunately, it has no GUI, so you'll have to run it in commandline form, inputting an avs file which contains the first line of the script MeGUI generates (just the input). It'll hopefully say what kind of source you have, in which case you can tell us and we can recommend some filters.
Upload a small sample of your source somewhere, so we can look at it.

[Hesse]

berrinam,

Thanks for the suggestion. I tried your tool with the following result:

E:\DVD\AMERICANDAD\DISC3\112\112_MEGUI>bautodeint --input 112.avs
BAutoDeint [info]: Number of sections of type `unknown': 137
BAutoDeint [info]: Number of sections of type `film': 14
BAutoDeint [info]: There are 0 sections with 0 frames moving.
BAutoDeint [info]: There are 7 sections with 1 frames moving.
BAutoDeint [info]: There are 6 sections with 2 frames moving.
BAutoDeint [info]: There are 13 sections with 3 frames moving.
BAutoDeint [info]: There are 7 sections with 4 frames moving.
BAutoDeint [info]: There are 14 sections with 5 frames moving.

Processing completed. Type is determined to be unknown.

This is the source AVS that I used previously generated by MeGUI.

# Set DAR in encoder to 4 : 3. The following line is for automatic signalling
global MeGUI_darx = 4
global MeGUI_dary = 3
DGDecode_mpeg2source("E:\DVD\AMERICANDAD\DISC3\112\112_MEGUI\112.d2v",info=3)
ColorMatrix(hints=true)
#Not doing anything because I have no idea what is going on
#crop
LanczosResize(720,480) # Lanczos (Sharp)
Undot() # Minimal Noise

As you can see, it is confused about the source type. I believe the source to be very bad, as I mentioned with the troubles of different deinterlacers.

If you or someone else could explain how to take a sample of the source to send to someone, I could try that also.

Edit:
Of course, after reading your message fully, I used the wrong avs script. I just reran it with only the DGdecode line pointing to the source, but the result from your program was the same.

[berrinam]

Aha! Cartoon sources always seem to cause troubles. Use ChopperXP to cut a bit of the VOB file so that you can upload it somewhere like http://rapidshare.de or http://savefile.com

[Carpo]

ok this has prob been asked b4 (and i have used search but trying to find the post search refers to in about 50 pages is a bit much :) )

what does no dct decimation do? and is it required - i see by default it is disabled and when i put the mouse over the box i dont get a little tooltip bubble telling me what its for.

i know im gonna get a response of "if you dont know what it is you dont need it" but it would be nice to know what it is and what it does :D

aslo can anyone suggest an all round quant matrix file to use ? at the moment i use eqm_avc_hr.cfg

MeGui Avisynth Script Genarator
At MeGui Avisynth Script Genarator, I open "E:\SES\[DVD-MV]S.E.S-meng.mpg". DGIndex's icon appears at taskbar, Maximize it, DGIndex don't do anything .
At DGIndex window, if I open file "E:\SES\[DVD-MV]S.E.S-meng.mpg" , DGIndex will do automatically without choosing "Save Project". And then Megui says "AVIsynth Error MPEG2source :unable to load D2V file E:\SES\[DVD-MV]S.E.S-meng.d2v "

There is a d2v file exist at E:\SES but its name is [DVD-MV.d2v

Thanks for the help everyone. I poked around in the settings and found the option to increase the amount of the source to analyze to determine the type. I changed it from 1% to 2% and it was able to successfully complete the analysis of the complete source. It came up with the TIVTC (similar to what you just said jellysandwitch).

I just processed the complete episode, and it looks great!

I wanted to take a moment to thank all the developers of MeGUI and the x264 codec. I tried MeGUI about 6 months ago had some troubles with quality, etc so I stuck with using AutoGK. MeGUI now is just great! The additional automated steps makes it easy for someone who doesn't want to go into the gory detail of setting up the AVS scripts, but allows the flexibility to do so for the others out there. And the quality of x264 is amazing. Keep up the great work everyone!

[Hesse]

Got another question. After generating the AVS script, then I'm using the "AutoEncode" option to automatically calculate bitrate and mux in the AC3 soundtrack into the MKV container. I'm also adding chapters and a name to the audiofile. However, when I view the file, the additional information is not there. Is it a bug or am I doing something wrong? I also like to name the video track with the name of the codec used, but this option is grayed out.

Thanks.

2k3 is essentially the same as xp sp2 with minor updates, megui/avisynth/x264 etc run fine on it. You might look into 2k3 SBS, if it's still cheaper than standard.

Update your megui, it should be on the zones tab.
